I tweeter Hertz ST 25K Neo sono davvero un salto di qualità per chi vuole un impianto audio auto serio. La prima cosa che si nota è la pulizia del suono sulle alte frequenze: sono estremamente dettagliati, brillanti ma mai fastidiosi se ben tarati. La resa sonora è molto precisa, con voci e strumenti che emergono chiaramente anche a volumi sostenuti. Il magnete al neodimio li rende compatti ma molto efficienti, quindi si riescono a installare facilmente anche in spazi ridotti senza rinunciare alle prestazioni. Se regolati correttamente con un buon crossover, non distorcono e mantengono una qualità stabile anche dopo sessioni di ascolto prolungate. Ideali per impianti SQ ma si difendono bene anche in setup più spinti. In generale un prodotto di fascia alta: non economici, ma la qualità si sente tutta. Consigliatissimi per chi vuole un impianto pulito, potente e ben definito. 🔊🔥⭐⭐⭐⭐⭐
